Synchronization on an object initialized with a literal
Reports synchronized blocks that lock on an object initialized with a literal.
String literals are interned and Character, Boolean and Number literals can be allocated from a cache. Because of this, it is possible that some other part of the system, which uses an object initialized with the same literal, is actually holding a reference to the exact same object. This can create unexpected dead-lock situations, if the lock object was thought to be private.
Example:
Locating this inspection

SynchronizedOnLiteralObject- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
Use the Warn on all possible literals option to report any synchronization on String, Character, Boolean and Number objects.
